To aLl whom it my concern.'

Be it known that I, EDWARD R. BARRETT, a citizen of the United States, residin at Detroit, in the county of Wayne and tate of Michigan, have invented certain new and useful Improvements in Adding-Machines, of which the following is a specification.

The invention relates to adding machines wherein a laterally shifting paper carriage is employed.

The principal object of the present invention is to provide for automatically returning such paper carriage to the right when imprints have been made in a predetermined number of columns. Thus in crosstabulating 'the machine will provide for numbers or amounts being printed one after another in a horizontal row with suitable spacing between and then the pa er carriage will be moved all the way back, t e paper being advanced to receive another horizontal row of numbers or amounts, and so on producing a series of parallel vertical columns.

In the form of embodiment of the invention herein shown and described a volute spring is employed for impelling the carriage and reversible gearing intervenes between the sprin and the carriage so as to provide for shi ting the latter in either direction. An escapement mechanism is arranged to bring about step-by-ste movement of the carriage to the left as t e crosstabulating proceeds and paper feeding mechanism comes into play when the last number or amount of a horizontal series has been printed, the gearing between the motor spring and the carriage being reversed as an incident to the line spacing or paper feed. Thereupon the carriage is moved back to the right by the spring and upon reaching the end of such movement the gearing 1s again automatically reversed so as to prepare for motion of the carriage from right to left as the escapement mechanism is operatedin connection with the printing of amounts.

In the drawings which accompany and form part of this specification Figure l represents a vertical section from front to rear of that portion of an adding machine with which the present invention is more intimately associated; Fig. I shows in side elevation certain parts which the section line of Fig. 1 cuts off Fig. 2 is a partial rear ele- 1 vation .of the machine with some parts broken awa and others represented in dotted lines; Fig. 3 represents a partial top plan View of the machine with some parts broken I away 'and others in horizontal section; Fig. 4 is a fragmentary rear elevation of certain parts which appear in dotted lines in Fig. 2; F ig'. 5 is a horizontal section taken on the line 5-5 of Fig. 2; Fig. 6 is a vertical section taken from front to rear farther to the left of the machine than the section on which Fig. 1 is taken; Fig. 7 is a horizontal lsection taken on the line 7-7 of Fig. 6; and Figs. 8 and 9 are fragmentary elevations of the reversing gears showing their-two different adjustments.

The invention is here shown as applied to the well-known Burroughs adding and listing machine but it is not to be understood as necessarily so limited in its application. As usual in this t-ype of machine when equipped with a laterally shifting carriage there is secured to the back panel of the casing a bracket 1765 on which the paper carriage 1717 is arranged to travel. The numeral 1793 designates the usual roller laten journaled in said carriage and it wi l be understood without illustration or detailed description that in the adding machine type will be set up opposite this platen and driven against it to print numbers upon paper which passes around the platen.

The numeral 1703 designates a rock-shaft journaled in the carriage and suitably connected with the roller platen so that by its oscillation said platen may be caused to turn step by step. There is secured to this rockshaft a plate 1723 which is also secured to a rod or bar 1706 extending parallel with the rock-shaft1703. A spring 1723e tends to uphold the plate and Vthe rod or bar and means resently to be described are` combined with the rod for the purpose of raising and lowering it to produce oscillations of the rock-shaft and consequent step-by-step* advance ofthe roller platen.

A vertically extending plate or bar 1723 is mounted to slide up and down on the back of the machine panel being held in place by screws 1723c passing through slots in the plate as shown in Fig. 2. This plate'has near its upper end a rearwardly progecting finger1723b underlying the rod 1700. Similar fingers 1724b overlie said rod but these latter fingers project from a late 1724 which is separate from the pate 1723* `though similarly slotted for the passage of the screws 1723c and adapted under some conditions to travel with said plate 1723*. When such conditions prevail the line spacing is produced by the lowering of the rod 1706 through the action thereupon of the fingers 17 24".

The plate 1723n moves down and u in every operation of the machine but it wi l be obvious that unless accompanied by the plate 1724 in such movement no movement of the rod 1706 will take place, the spring 1723e holding it up. The means for causin reciprocation of the plate 1723* comprise a lever 1720 pivoted intermediate its length to a fixed part of the machine and carrying at its forward end a roll 1720* occupying a cam slot 121d in a plate 121 secured to the familiar Burroughs rock-shaft 100. At its rear end this lever 1720 is slotted to receive a pin 1715b in a lip or flange 1723d of the plate 1723*. It will be obvious that through these connections the said plate will be moved up and down by the oscillation of the rock-shaft 100, such oscillation taking place in every operation of the adding machine.

Before proceedin to describe the means whereby the two p ates 1723* and 1724 are connected and disconnected itwill be well to first describe the means employed for determining different column positions of the paper carriage. A rock-shaft 1704 is journaled in the lower part of said carriage and there are adjustably secured to it at different points throughout its length a series of stop fingers 17 92, the means here shown for so securing these stop fingers to the rock` shaft consisting in set screws 1762 engaging a longitudinal groove in the shaft. Two different lengths of stop fingers are employed but all of the fingers are adapted to abut the vertical shoulderof a stop plate 1716* screwed to the back panel of the machine as shown in Fig. 2. Thus the position of the stop fingers on the rock-shaft determine the column positions of thecarriage. `Two different lengths of stop fingers are em loyed for the purpose of determining whet er or not after the printing of a number in a certain column line spacing or paper feed shall ensue. The stop plate 1716* stands a distance away from the back panel of the machine casing and the plates 1723* and 1724 pass between the stop plate and such panel. The longer fingers 1792 project forwardly of the stop plate but the shorter fingers do not, and devices presently to be described are combined with the plates 1723* and 1724 so as to effect disconnection of said plates whenever one of the longer fingers is engaged with the stop plate 1716*. Hence under such conditions the plate 1724 will not accompany the plate 1723* in its reciprocations and no line spacinr will take piace. However, when one of tie shorter fingeis 1792 is engaged with the stop plate 1716*,

the two lates 1723* and 1724 are connected and the atter will move with the former to effect line spacing. It is further to be noted thatthe reciprocations of thc plate 1723* when one of the lon er fingers 1792 is engaged with the stop p ate 1716*, will cause a rocking of the shaft 1704 by action against the stop finger where it extends forward of the stop plate, all as will now be specifically described.

There is pivoted to a lower offset portion of the plate 1723a a dog 1715*, the latter movable laterally and held to the right by a spring 1715c (Fig. 2). A strip 1724c secured to the plate 1724 is shouldered as shown at 1724d in Fig. 2 for the engagement thcreover of a flange 1715d at the upper end of the dog 1715*. It will be seen that when the parts are so engaged the plate 1723* in moving downward will carry with it the plate 1724. It will be observed, however, that the dog 1715* extends between the stop plate 1716* and said plate 1724 and when engaged with the shoulder 1724d extends to the right beyond the vertical shoulder of the stop plate. The protruding end of one of the longer stop fingers 1792 before reaching the latter shoulder in the movement of the carriage to the left will encounter the vertical edge of the dog and move the latter a ainst the stress of its 4spring 1715c thereby isengaging the flange of the dog from the shoulder 1724d and hence disconnecting the two plates 17 24 and 1723*. `Therefore as the plate 1723* descends in an operation of the machine it does not carry with it the late 1724, the dog 1715* simply assing own alongside the strip 1724. ivlien the flange of the dog passes below the stop finger 1792 it snaps under the saine so that when the plate 1723* rises as the operation of the machine continues this flange will lift the stop finger and disengage it from the shoulder of the stop plate 1716* whereupon the carriage will jump to the left until the next stop finger comes against said shoulder of the stop pllate. Should this next Succeedin stop finger be a short one, the flange of t e dog which in the rise of the plate 1723* has returned to engagement with the shoulder 1724", will remain so engaged because this shorter stop finger does not act against the dog. Hence in the next ensuing operation of the machine the plate 1724 will descend with the plate 1723* andthe paper feed will be effected. Of course no further automatic shift of the paper carriage to the leftI will be brought about in the manner before described since the dog does not encounter the short stop finger in rising. So far as the mechanism already described is concerned listing of amounts in a single column would then continue indefinitely. However, the present invention provides for an automatic return of the carriage to the right at the, conclusion of an operation of the machine when a short. stop finger is fixing the column position of the paper carriage.

The carriage las secured to its front side above the bracket 1765 a horizontal rack 2 which is in mesh constantly with a gear 3 formed upon the periphery of a drum-like member 4 arranged to turn freely upon a vertical shaft 5 secured at its upper end in a bracket 6 on the rear panel of the machinel casing (Figs. 1, 3 and 6). An internal gear 7 is secured to the inverted rim of the drumlike member 4 and this internal gear meshes with a transmission gear 8 journaled upon a screw stud 9 on a second bracket 1.0 secured to the back panel of the machine casing (Fig. 6), this bracket also affording a support for the lower end of the shaft 5. This transmission gear is more than double the width of the internal and an intermediate gear 11 of the same width as the transmission gear (Figs. 8 and 9) meshes with a different Ortion of the toothed periphery of the latter from that portion which meshes with the internal gear. This intermediate gear is mounted upon the bracket 10 inthe same manner as is the transmission gear but does not engage the internal gear. A shift gear 12 of the same width as the internal gear is centrally located with reference to the latter and adapted to mesh alternately with the transmission gear 8 and the intermediate gear 11, becoming engaged with one before disengagement from the other thus always kept in register. It will be obvious that when directly in mesh with the gear 8 this shaft gear when turned will rotate the member 4 with its gear 3 in a direction onposite that in which rotation will be caused when said shift gear is in mesh with the intermediate gear l1. The shift gear 12 is part of an annularly grooved sleeve 13 splined to the hub 14 of a drum 15 incased by the member 4 all as shown in Fig. 6. Said drum contains a volute spring 16 whose outer end is in frictional engagement with the inner circumferential wallof the drum and whose inner end is secured by a screw 17 to a sleeve 18 journaled upon the shaft'5 and itself constituting a bearing for the hub of the drum 15. The sleeve 18 constitutes an anchorage for the spring and the latter tends to rotate the drum 15 and hence the shift gear l2 through the splined connection already described. It will be obvious that through the reversible gearing described the spring can be caused to impel the carriage in either direction.

Means are provided for keepingthe spring properly'tensioned, as follows: A spur gear 19 is secured to the'lower end of the sleeve 18 and meshes with a similar gea-r 20 011 the upper end of a vertical shaft 21 journaled in a bearing provided by the bracket 10 and in a bearing provided by a lower bracket 22 secured to the back panel of the machine casing. This shaft carries at its lower end a beveled gear 23 in mesh with a beveled gear 24 secured to a horizontal shaft 25 journaled in a bea-ring provided by the bracket 22 (F ig. 5). A ratchet-wheel 26 is secured to this shaft 25 and a spring-held pawl 27 vibrating with the lever 1720 engages said ratchet as shown in Fig. 1. Thus whenever the machine is operated the ratchet-wheel 26 is turned and through the described gearing the sleeve 18 is turned in a direction to wind up the spring. A retainingpawl 28 engages the ratchet to pres vent retrograde movement, said pawl being spring-held and pivoted upon a bracket 29 secured to the back panel of the machine casing and embracing the hub of the ratchet as shown in Fig 5. The frictional engagement of the s ring 16 with the drum prevents overwin ing.

Passing now to the meanstfor controlling the reversible gearing from the line spacing or paper feedmg devices hereinbefore described, a fork 30 engages the circumferential groove of the sleeve 13, being pivoted at 31 to a lower portion 0i the bracket 6. A spring 32 draws down the rearward end of this fork thus elevating its forward end and holding the shift gear 12 in mesh with the transmission gear 8. Under this adjustment the spring 16 tends to impel the paper carriage toward the left. On the rear end of the' fork there is mounted a roller 33 which is adapted to be acted upon by a cam 34 (Fig. 4), said cam being formed on a horizontal slide bar l,35 arranged on the inner side of the back panel of the machine casing. This slide bar is suitably guided in its movements by shouldered studs 36 and 37 engaging slots 38 in said panel (Fig. 2). The stud 36 coperates with a gravity wipe plate-39 pivoted upon the line spacing plate 1724 as shown in Fig. 2 and normally held by its Weight against a stop pin 40. In the descent of said plate 1724 the wipe plate or pawl 39 simply flips idly past the stud 36 but upon the rise of said plate 1724- the cam edge of the wipe plate acts against the stud 36 and thrusts the bar to the left thereby causing its cam 34 to rock the fork 30 and shift the gear 12 out of engagement with the transmission gear 8 and into engagement with the intermediate gear 11 as shown in Fig. 9. Thereupon the spring 16 acts to ret-urn the carriage to the right. Near its left-hand end the carriage is provided with a tappet-piece 41 preferably pivoted and ats tached to a spring 42 for cushioning purposes. When the carriage is thrown to the right by the spring upon the described reversal of the gearing this tappet-piece 41 will encounter the stud 37 just as the carriage reaches the limit of its movement and 'by impact against said stud will thrust the bar 35 t0 the right withdrawing the cam 434 from engagement with the roller 33 whereu'pon the spring 32 restores the reversible gearing to itsv first adjustment so that the spring 1G again tends to impel the carriage to the left.

It will be understood that the rock-shaft 1704 is spring-actuated to enforce engagement of its stop fingers with the stop plate. As the carriage is drawn to the right the several st`op fingers will slide over the inclined ed e 1716b of the stop plate and of course w en the reversal thereafter takes place in the carria e shifting ear the stop finger farthest to t e left will iold the lcarriage in position for printing in the first column. The do 1715 is beveled en top as shown at 1715d 1n Fig. 2 so that the longer stop fingers will pass. The means here shown for yieldin ly enforcing engagement between the stop ngers and the stop plate com )rise an arm 1717 (Fig. 1*) secured to t e rock-shaft 1704 and a spring 1784 connecting said arm with the carriage. i

It has been hereinbefore stated that suitable connections are provided between thev rock-shaft 1703 and the platen for turning the latter step by step. The connections here shown comprise an arm 1722, a stud 1722a carried by said arm, a link 1722b hav ing a curved slot 17 22 receiving said stud, a stud 1747 adjustable in said slot to be acted against by the stud 1722, an arm 1713 pivoted concentrically with the platen and pivotallyk r4connected with the link 17 22", a ratchet-wheel 1728 secured to the platen, and a spring-held lpawl 17 22d engaging said ratchet and pivotally connected with the arm 1713 where the latter joins the link 1722". It will be seen that with this arrangement oscillating of the shaft 1703 will y.cause the stud 1722 to retract the pa'wl 1722d over the teeth of the ratchet wheel, by

impact against the stud 1747, the number of teeth depending upon adjustment of the latter stud in the slot 1722, and that the stud 1722 will then effect the feed by acting against the bottom of the slot.

Provision is made for disconnecting the paper feed `or line-spacing mechanism when 'the carriage is to be taken off for inspection or other purposes, as follows: The feed lever 1720 has secured to it an ear 1720 (Fig. 5) pivoted in the bifurcation of a stub-shaft 1720b which is journaled in a suitable bear ing on the machine frame. 'A spring 17 20c interposed between the ear 1720l and the base of the said bifurcation normally holds the lever 1720 in engagement with the stud v 1715*. The lever can be readily disengaged from said stud` by pressing against the rear end of the lever in o position to the spring. Thel pawl herein fore described as va'brated by the feed lever is not mounted directly upon the same but u n an arm 1720d secured to the shaft 1720 which shaft of course oscillates as the lever is vibrated.

While the above-described construction is well adapted to fulfil the objects of the invention still it is susceptible of considerable modification within-the sco of the invention as defined by the a n ed claims. For example it is not essentla that'the` carriage be moved both wa s by the spring nor is it essential that t e motive power for moving the carriage be that of a spring, so far as concerns the broad ideaof causing the carriage to successively occupy a series of'columnar positions and then automatically return to its initial position.
